Lab question: cleaning glass

Nov 04, 2003 6 Replies

Hi!



How can glass (beakers, flasks, etc.) be cleansed of acrylic polymers(*) which are insoluble in water without using a lot of organic solvents? I am searching for an environmentally friendly way of cleaning lab equipment.



TIA, Oliver



(*) highly viscous, strongly adherend, glue-type polymer


Pyrolytacl and then mechanical...

heat it ub and then clean the Glass with a brush...

I am not a bug I am a undocumented feature

We use ulta sound to clean ours but i do not know off hand what the liquid is in the tank it could be water.

I would try methanolic KOH. Frank

you may try that fill the flask (or whatever it is) with acetone then dip it in ultrasonic bath

good luck

Ozgur Eylem science is a key with this key you can open heavens door but the same key also opens hells doors too... R.Feynman

You are a bit late... ;-)

It is not possible to fill the flask completely with acetone and then you have still spots with some tacky residue (or acetone-spills dry: same problem).

I have tried most of the suggestion and I will stick to the methanol(ispropanol/ethanol)/KOH solution.

Regards, Oliver
